I keep hearing about this growing white supremacist threat, and while in some dark corners of the internet there do seem to be some examples of it, I can't say that I have any reason to think it's growing. What I've seen growing is the willingness of supposedly anti-racist groups to label as white supremacist anyone who disagrees with them on any issue, which is not helpful.
I'd be interested to learn why some seem to find this comment objectionable.
